You may update the payment method on your subscription at any time from your Account Dashboard at www.hookedonphonics.com/dashboard to prevent interruption of shipments. To see your payment details, tap Manage Payments from the menu at the top right.
Then tap the subscription for which you'd like to update your payment method, and tap the type of payment method you'd like to add, and tap Submit.
If you have any outstanding payments on your subscription account, you'll be prompted to make a payment now, if you wish. Otherwise, this payment method will be saved on file for future shipments.
